USING INTERVIEWS IN A RESEARCH PROJECT

Introduction

The interview is an important data gathering technique involving verbal communication between the researcher and the subject. Interviews are commonly used in survey designs and in exploratory and descriptive studies. There are a range of approaches to interviewing, from completely unstructured in which the subject is allowed to talk freely about whatever they wish, to highly structured in which the subject responses are limited to answering direct questions. The quality of the data collected in an interview will depend on both the interview design and on the skill of the interviewer. For example, a poorly designed interview may include leading questions or questions that are not understood by the subject. A poor interviewer may consciously or unconsciously influence the responses that the subject makes. In either circumstance, the research findings will be influenced detrimentally. It is often assumed that if one is clinically trained and used to dealing with patients, that this is sufficient training to carry out interviews with patients and others for research purposes. Although there are some areas of overlap in terms of the basic communication skills required, it should be acknowledged that for research some different skills are required. The context is also important, since in a clinical setting, there is a particular relationship between a patient and clinician. It is possible that in this routine setting the patient would not be prepared to answer all the questions in a completely honest manner. So it may well be worthwhile thinking about the interview from the respondent's point of view and considering carefully who would be the most appropriate person to conduct the interview and in what setting. There may be a conflict of roles, for example, therapeutic versus research; or even an unconscious adoption of roles that could affect the quality of the data collected.

LEARNING OBJECTIVES Having successfully completed the work in this pack, you will be able to: ? Describe the skills required to undertake a structured, semi-structured or unstructured

interview. ? Summarise the advantages and disadvantages of face-to-face and telephone interviews. ? Outline the ways in which different types of interview data can be analysed.
